Description

FIELD OF THE INVENTION

The present invention relates, in general, to multimedia processing and, in particular, to a multimedia playback system in a portable device having an integrated controller.

State of the art

Advances in technology have led to the creation of more miniature and more powerful personal computing devices. For example, there are currently a variety of portable cell phones, personal digital assistants (PDAs) and pagers, which are small in size, light in weight and easy to use. Typically, these devices have a built-in controller with limited memory resources. For example, the amount of available memory may be limited by the small size of the device.

However, it is increasingly required that these devices process large amounts of data and run more complex programs. For example, users require remote access to interactive programs, such as gaming programs, which require the portable device to provide fast and efficient playback of multimedia applications and content (content). For example, users would like to use their portable devices to view and listen to multimedia content, such as video clips, cartoons, movies and audio recordings, such as music content provided in MP3 format.

To play multimedia content on a portable device, you must manage the playback resources of the device. For example, one type of portable device may include a small, low-resolution display screen or speaker, and another type of portable device may include a larger, higher resolution display and stereo with two speakers. Thus, each type of portable device can have different media playback resources with which you can play multimedia content. Therefore, to provide multimedia content for use by a wide range of portable devices having different configurations and playback resources, it is necessary to solve compatibility problems.

One method used to solve compatibility problems requires the multimedia content to have a format that is, in particular, compatible with the playback resources available on the portable device. For example, if a content developer wants to create video content for use in a particular portable device, the developer adjusts the video content to be exactly compatible with the video playback resources available in the portable device.

Unfortunately, it is expensive and inefficient to create multimedia content tailored for each portable device on which the content is to be played. For example, a content developer will need to modify content for various portable devices and thus generate multiple versions of the same content. In addition, the content developer is forced to constantly update his content as new playback resources become available.

Therefore, we need a system that allows you to play multimedia content on various portable devices without the need for adaptation, taking into account the various playback resources available in each device. The system should be able to play all types of multimedia content and provide an extensible architecture that allows you to play new multimedia formats as they become available.

SUMMARY OF THE INVENTION

According to one or more embodiments, a multimedia system is provided, including methods and apparatus for reproducing multimedia content on a portable device. A portable device may be, for example, a cell phone with an integrated controller and limited memory resources that executes program instructions for playing multimedia content using the available playback resources of the device. According to one or more embodiments, a multimedia system is a small and efficient implementation that uses few resources and, in particular, is well suited for use in portable devices having integrated controllers with limited memory resources.

According to one embodiment, the system comprises a plurality of format handlers for managing device playback resources. Each format handler is designed to process multimedia content having a specific format, and thus to control the playback resources of the device for reproducing this content. For example, each format handler plays a (in a certain way formatted) multimedia audio or video file (plays and understands it). The format handler determines what resources are needed by the content, reads the file and calls the necessary resources. The portable device contains a high-level application program interface (API) that the format handler uses to complete the task. Each format handler may be included as part of a multimedia system in a portable device during manufacture, or may be loaded dynamically. Therefore, according to one or more embodiments, a plurality of format handlers can be used, which allows multimedia content to be played in various portable devices without the need to tailor the content depending on the playback resources available on each device. In addition, the multimedia system provides an extensible architecture that allows you to expand the system by adding new format handlers to play back new types of content as they are developed.

The architecture of the multimedia system is beneficial to both multimedia users and developers. For example, it allows developers to write their own format handlers for use on a wireless platform. And multimedia users benefit, because the system provides a simple interface that allows you to play all types of content without having to know the exact configuration of the playback device.

According to one embodiment, a method for reproducing multimedia content in a portable device having an integrated processor is provided. The portable device further comprises one or more playback resources. The method consists in generating a multimedia object based on the multimedia content, associating a format handler with the multimedia object, and controlling the selected playback resource using the format handler to play the multimedia content from the multimedia object.

According to another embodiment, a multimedia system for reproducing multimedia content in a portable device having an integrated processor is provided. A portable device contains one or more playback resources. The multimedia system contains media creation logic, which is designed to generate a multimedia object based on multimedia content. The system also contains selection logic, which is designed to associate a format handler with a multimedia object. The system also contains format processing logic that is designed to control the selected playback for reproducing multimedia content from a multimedia object.

According to yet another embodiment, there is provided a computer-readable storage medium comprising computer-executable instructions for playing multimedia content in a portable device having an integrated processor. The portable device further comprises one or more playback resources. When executing the commands, a method is implemented which consists in generating a multimedia object based on the multimedia content, associating the format handler with the multimedia object and controlling the selected playback resource using the format handler to play the multimedia content from the multimedia object.

According to yet another embodiment, there is provided a multimedia system for reproducing multimedia content in a portable device having an integrated processor. The portable device further comprises one or more playback resources. The multimedia system comprises means for generating a multimedia object based on multimedia content. The system also includes means for associating a format handler with a multimedia object.

The device 102 can also receive multimedia applications or content over a wireless network 108. For example, multimedia applications 112 and 114 can be downloaded to the device 102 from the network server 106. Additionally, multimedia content 116 can also be downloaded to the device 102 from the network server 106.

According to one embodiment, the device 102 is also connected directly to the local system, for example, the local workstation 118, through the forward link 120. According to one embodiment, the local workstation 118 downloads multimedia applications or content to the device 102 using the forward link 120. For example, multimedia application 122 is downloaded to device 102 from workstation 118 using communication line 120.

The IMedia system 104 may boot from the server 106 to the device 102 and operates on the device 102 to play multimedia applications or content. In another embodiment, IMedia system 104 may be loaded into device 102 from workstation 118 via communication line 120, or may be installed in the device during manufacture.

According to one embodiment, the IMedia system 104 is provided on a computer-readable storage medium, such as a floppy disk, and is loaded into the system 118 for transmission to the device 102. According to another embodiment, the IMedia system 104 may be stored in a computer-readable storage device, for example, on a memory card (not shown) that connects directly to the device 102, so that the IMedia system 104 can run on the device 102. Thus, the device 102 can receive the IMedia system 104 wirelessly nd transmission, wired transmission, or by retrieving it directly from the memory.

The network 100 may also include other types of portable devices, for example, other types of wired and wireless portable devices, and these devices can communicate with the server 106 and any other network objects using various types of networks and communication architectures, private and public switched networks and non-switched networks, direct lines of communication, and any combination thereof, for downloading one or more embodiments of the IMedia system 104 for playing multimedia content.

FIG. 2 is a functional block diagram illustrating one embodiment of an apparatus 102 that includes one embodiment of an IMedia system 104 that is designed to play multimedia content. Apparatus 102 includes processing logic 202 that is connected to internal data bus 204 and stack memory 216.

During operation of the device 102, the processing logic 202 executes program instructions stored in the command memory 206 to generate a work environment 220. Work environment 220 may be a BREW environment or other suitable work environment. To facilitate the execution of instructions, processing logic 202 uses stack memory 216 to temporarily store program data or instructions. For example, processing logic 202 may store constants, variables, program addresses, pointers, instructions, or other information items in stack memory 216. According to another embodiment, processing logic 202 may temporarily store information in dynamic memory 210. Dynamic memory contains virtually any type of memory suitable for storing and retrieving information by processing logic 202.

According to one or more embodiments, the processing logic 202 comprises a CPU, a gate array, hardware logic, software, or a combination of hardware and software. Thus, the processing logic 202 generally contains logic for executing machine-readable instructions.

Command memory 206 comprises RAM, ROM, flash memory, EEPROM, or any other suitable type of memory, or a combination thereof. According to one embodiment, the command memory 206 is located inside the device 102, and according to another embodiment, the command memory 206 comprises a removable memory card or memory device that can be selectively connected to the device 102 and thus connected to the internal bus 204. Thus , the command memory 206 may comprise virtually any type of memory capable of storing instructions that can be executed by processing logic 202.

The user interface 212 accepts user input, for example, from a keyboard, pointing device, touch pad, or other input mechanisms, which allows the user to interact with the device 102. The display logic 216 contains logic for outputting information to the display device. For example, a device may include an LCD, LED, or other type of display resource. Audiology 218 includes logic for outputting audio information to the speaker (s) of the device, remote (s) speaker (s), or an audio system or other type of audio resource. For example, a pair of remote speakers may receive an input from audiologist 218 to reproduce audio information for a device user. Thus, the display logic 216 and the audiologist 218 may include hardware and / or software in any combination so that the device 102 can reproduce visual or audio information for the user of the device.

An I / O interface 214 is for transmitting and receiving information between device 102 and external devices, systems, and / or networks. For example, according to one embodiment, the input / output interface 214 comprises a radio transceiver circuit (not shown) that is designed to transmit and receive information over a wireless data network using, for example, communication line 106. For example, the transceiver contains a circuit that modulates information, obtained from the processing logic 202, and converts the modulated information into high-frequency signals suitable for wireless transmission. Similarly, the transceiver also includes a circuit for converting the received high-frequency communication signals into signals suitable for demodulation and subsequent processing by the processing logic 202.

According to another embodiment, the input / output interface 214 comprises a transceiver that is designed to transmit and receive information over a wired communication line, such as a telephone line, for communicating with a remote system in a public data network, such as the Internet.

The input / output interface 214 may also comprise a circuit (eg, serial or parallel port) for communication with a printer or other local computer or device, such as a floppy disk or memory card. Thus, the input / output interface 214 may comprise any type of hardware, software, or combination thereof, so that device 102 can communicate with other local or remote devices or systems.

During operation of the device 102, execution of program instructions by processing logic 202 leads to the generation of IMedia system 104. For example, IMedia commands that generate the IMedia system 104 can be stored in the command memory 206. The IMedia system 104 interacts with the working environment 220 to play multimedia applications and content on the device 102. For example, multimedia applications and content can be downloaded to the device 102 through wireless network 108 and stored in memory 208. In one embodiment, the IMedia system 104 retrieves the multimedia content stored in the memory 208 through the internal bus 204 and processes the content to read it into device 102 by interacting with the device’s playback resources (ie, display logic, audiology, etc.) through the operating environment 220. System 104 is also designed to process and play streaming multimedia content. For example, streaming multimedia content downloaded from the network 108 to the device 102 is played on the device 102 using the IMedia system 104.

Note that the configuration of the device 102 is only one of the configurations suitable for implementing one embodiment of the IMedia system 104 for playing multimedia applications and content. You can also implement the IMedia system 104 using other devices or device configurations within the scope of the present invention.

Device 102 includes proprietary equipment 302 that includes processing logic 202 and optionally may include a multimedia processor 304, particularly for processing multimedia information. It is assumed without further description that the native equipment 302 contains logic for operating the playback resources of the device (i.e., display logic 216, etc.) and that the processing logic 202 and the multimedia processor 304 can act to control these resources.

The device 102 also includes proprietary multimedia software 306, which includes modules audio1 308, audio2 310, and video 312. These modules represent low-level software modules that are used to directly communicate with native equipment 302 to manage selected playback resources. For example, video module 312 communicates with multimedia processor 304 to manage video playback resources. Although one embodiment is shown, it is also possible to have fewer or more multimedia software modules 306, and these modules can communicate with all types of proprietary equipment 302. Thus, other configurations of proprietary hardware 302 and software 306 are possible within the scope of the invention.

In operation, device 102 executes program instructions to generate a work environment 220, which, according to one embodiment, is a BREW environment. You can then run IMedia commands to generate the IMedia 104 system to play multimedia content in conjunction with the work environment. For example, IMedia commands may be downloaded to the device via wireless network 108 and stored in command memory 206.

The IMedia system 104 is designed to abstract the processing of multimedia content and determine the structure of multimedia interfaces. According to one embodiment, the IMedia system 104 is intended to provide the following features.

1. Provides general and easy access to multimedia features and capabilities of the device.

2. Separates multimedia APIs of the level of complex specialized integrated circuits (SIS) and provides resource management.

4. Optionally, retrieves the media type based on the file extension, the contents of the file, or the signature in the file.

IMedia system 104 includes media creation utility 324, 326 media data structure, and format handlers 314, 316, 318, and 320. As part of the IMedia system 104, an IMedia abstraction 328 is shown that illustrates the basic IMedia object that is created by the operation of the IMedia system 104. The following is a detailed description of the components of the IMedia system.

Abstract IMedia

Abstract 328 IMedia is an abstract interface that allows you to register and process a type of multimedia content. IMedia Abstract 328 maintains a link to media in the 326 media structure.

Media structure

The media data structure 326 is intended to encapsulate a source or receiver of media data. This allows the IMedia system 104 to create a media stream from various sources or to various destinations. According to one embodiment, the media data structure 326 is generated from the data structure logic, which comprises processing logic 202 executing program instructions to generate the media data structure 326 in the memory 210.

Media Creation Utility

Utility 324 create media performs several functions. First, the media creation utility 324 is for receiving multimedia applications or content for playback. For example, multimedia applications or content can be stored in memory 208, and this content includes a functional call utility 324 create media. Secondly, the media creation utility 324 processes the multimedia content to create the IMedia object 328 based on the information contained in the media 326. After creating the IMedia object, it sets the media data and puts the IMedia object in a ready state. According to one embodiment, the media creation utility 326 is generated from the media creation logic, which comprises processing logic 202 executing program instructions to create an IMedia object 328 in memory 210 and performs the functions of the media creation utility described herein.

According to one embodiment, the media creation utility 326 includes a selection logic that includes processing logic 202 executing program instructions to select a format handler to associate with the IMedia object 328 and perform the other functions described herein. For example, selection logic evaluates a data structure 326 associated with media content to determine which format handler to select.

Format handlers

According to one embodiment, the IMedia system 104 comprises a plurality of format handlers (PFs). For example, IMedia system 104 includes MIDI 314, MP3 316, MPEG4 318, and ADCPM 320 format handlers. These format handlers provide interfaces 322 between IMedia objects 328 and the media and hardware of multimedia playback device 102. In one embodiment, the format handlers interrupt the general instruction set so that multimedia applications or content can use the same commands to instruct format handlers to perform similar tasks, such as play, pause, rewind, etc. You can use any number of format handlers, and you can add new format handlers to play new types of multimedia content. According to one embodiment, the format handlers are formed from format processing logic that comprises processing logic 202 executing program instructions to perform the functions of the format handlers described herein.

According to one embodiment, a common set of instructions causes the format handlers to play multimedia content and provides a mechanism for translating parameters and status. The following is an example of the commands included in the common set of commands.

one. IMedia_SetMediaParm () sets formatting parameters 2. IMedia_GetMediaParm () gets parameters from OF 3. IMedia_SetMediaData () sets media four. IMedia_GetMediaData () receives media 5. IMedia_GetClassID () gets class id 6. IMedia_GetState () gets state 7. IMedia_RegisterNotify () registers callback with OF 8. IMedia_Play () issues a play command to the formatting object 9. IMedia_Stop () issues a stop command on OF 10. IMedia_SetRect () sets video parameters

For example, the IMedia_SetMediaParm () command may be included in an IMedia object to instruct the format handler to specify specific parameters, settings, or variables associated with the format handler. For example, using the IMedia_SetMediaParm () command, you can set parameters associated with a format handler for playing MPEG video. In other embodiments, specific format handlers may also interpret additional instructions (not shown above) that may be included in the IMedia object 328 and which may be used to control a particular managed resource function.

According to one embodiment, the format handler is a program operating in a portable device as part of the IMedia system 104. According to another embodiment, the format handler may be a combination of hardware and software. In addition, format handlers can be added to the IMedia system as they become available, so the IMedia system is extensible and is able to play new types of multimedia content as they become available.

In the process, format handlers are registered (their own MIME type) using the working environment, and multimedia applications can detect them by querying the MIME type or by viewing the list of supported (registered) format handlers in the system. Each format handler provides a selection of functions, including, but not exclusively, the following.

1. Providing an application program interface (API) that:

but. Performs playback and recording of multimedia content, including such management functions as search, pause, resume, etc .;

b. Sets and / or gets the audio and video control parameter;

from. Handles asynchronous events from an IMedia object.

2. Transmits asynchronous media events through a registered callback function.

3. Manages the playback resources of the multimedia device.

4. Controls a state machine that has an extension due to derived classes.

FIG. 4 shows one embodiment of a state machine 400 controlled by a format handler for playing multimedia content, for example, a format handler 318. The initial state of the format handler is idle state 402. After the format handler is associated with the IMedia object, the format handler transitions to the state ready 404. From the ready state 404, the format handler can either go to the playback state 406 or the recording state 408, depending on the commands associated with the multimedia content. From the playback states 406 and the recording 408, the format handler can transition to the paused playback 410 or the paused recording 412, from these states it is also possible to return to the playback 406 and recording 408. The format handler can also stop 414 and return to the ready 404.

Therefore, using the state machine 400, each format handler can control the playback resources of the device to play multimedia applications or content (IMedia object) associated with this format handler. According to another embodiment, the format handler may also implement a state machine other than that shown in FIG. 4. In addition, in other embodiments, implementation, you can specify additional conditions that can be used in the playback process.

5, one embodiment of a method 500 for reproducing multimedia content in a portable device is shown.

At block 502, a multimedia application or content is created using IMedia constructs so that it can be played on a portable device. For example, application developers create IMedia objects using media creation utility 324. The number of IMedia objects and capabilities, such as simultaneous playback or recording, vary by device. All IMedia objects obey the main state machine shown in Fig. 4. According to one embodiment, the following steps can be used to create and use an IMedia object.

1. Create a media data structure and initialize it based on the media source / receiver. AEEMediaData is defined as follows.

typedef struct { AEECLSID clsData; // Media Type Void * pData; // Context-dependent data (see // Table) uint32 dwSize; // Context-dependent data (see // Table) } AEEMediaData;

2. Initialize the members of the above structure based on the information given in the following table.

clsStream pData dwSize Comments MMD_FILE_NAME File name 0 For playback and recording. IMedia does not open the file, but the file name is passed to the SIS-level API that opens the file. MMD_BUFFER Buffer pointer Buffer size For playback and recording. The buffer should contain full media data. MMS_Source ISource Full data size or 0 Real-time streaming.

At block 504, multimedia content is downloaded to a portable device for playback. For example, the application or content may be downloaded to the device via a wireless data network 108. Content can be streamed or stored in memory and played later.

At block 506, a media data structure is created and initialized based on the characteristics of the media source or receiver included in the received content. For example, the structure of the media is stored in the structure of 326 media. According to one embodiment, the media type is derived based on the file extension, the contents of the file, or the signature included in the file.

At block 508, an IMedia object is created using the associated data structure. For example, to create an IMedia object, 324 media creation utility is used. The IMedia object returns in ready state 404.

At block 510, an optional step may be performed to register the notification function, if necessary for received asynchronous events from the IMedia object.

In block 512, the IMedia object is mapped to a format handler, and the multimedia application or content is rendered on the portable device. For example, a format handler may provide any of the functions of the state machine 400 for reproducing multimedia content.

At block 514, after the content is reproduced and the IMedia object is no longer needed, it is cleared.

Implementation example

The following is an example implementation illustrating how, according to one embodiment, an IMedia object is created. An example includes references to corresponding process units shown in FIG. 5, and it is assumed that the operating environment used by portable device 102 is a BREW environment. Thus, "CApp" is an example of the global structure of BREW applets.
