Up to this point, mobile terminals have been described in terms of their functionality. Hereinafter, a slide-type mobile terminal among various types of mobile terminals, such as a folder-type, bar-type, swing-type, slide-type mobile terminal, and the like, will be described as an example for the sake of brevity. Accordingly, the present invention can be applied to any type of mobile terminal, and is not limited to a slide type mobile terminal.

The mobile terminal 100 as shown in fig. 1 may be configured to operate with communication means such as wired and wireless communication means and satellite-based communication means that transmit data via frames or packets.

A communication apparatus in which a mobile terminal according to the present invention is operable will now be described with reference to fig. 2.

Such communication devices may use different air interfaces and/or physical layers. For example, the air interface used by the communication device includes, for example, Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), Code Division Multiple Access (CDMA), and universal mobile telecommunications device (UMTS) (in particular, Long Term Evolution (LTE)), global system for mobile communications (GSM), and so forth. The following description relates to a CDMA communication device, as a non-limiting example, but such teachings are equally applicable to other types of devices.

Referring to fig. 2, the CDMA wireless communication apparatus may include a plurality of mobile terminals 100, a plurality of Base Stations (BSs) 270, Base Station Controllers (BSCs) 275, and a Mobile Switching Center (MSC) 280. The MSC280 is configured to interface with a Public Switched Telephone Network (PSTN) 290. The MSC280 is also configured to interface with a BSC275, which may be coupled to the base station 270 via a backhaul. The backhaul may be constructed according to any of several known interfaces including, for example, E1/T1, ATM, IP, PPP, frame Relay, HDSL, ADSL, or xDSL. It will be understood that an apparatus as shown in fig. 2 may include a plurality of BSCs 275.

Each BS270 may serve one or more sectors (or regions), each sector covered by a multi-directional antenna or an antenna pointing in a particular direction being radially distant from the BS 270. Alternatively, each partition may be covered by two or more antennas for diversity reception. Each BS270 may be configured to support multiple frequency allocations, with each frequency allocation having a particular frequency spectrum (e.g., 1.25MHz,5MHz, etc.).

The intersection of partitions with frequency allocations may be referred to as a CDMA channel. The BS270 may also be referred to as a base transceiver sub-assembly (BTS) or other equivalent terminology. In such a case, the term "base station" may be used to generically refer to a single BSC275 and at least one BS 270. The base stations may also be referred to as "cells". Alternatively, each sector of a particular BS270 may be referred to as a plurality of cell sites.

As a typical operation of the wireless communication apparatus, the BS270 receives reverse link signals from various mobile terminals 100. The mobile terminal 100 is generally engaged in conversations, messaging, and other types of communications. Each reverse link signal received by a particular base station 270 is processed within the particular BS 270. The obtained data is forwarded to the associated BSC 275. The BSC provides call resource allocation and mobility management functions including coordination of soft handoff procedures between BSs 270. The BSCs 275 also route the received data to the MSC280, which provides additional routing services for interfacing with the PSTN 290. Similarly, the PSTN290 interfaces with the MSC280, the MSC interfaces with the BSCs 275, and the BSCs 275 accordingly control the BS270 to transmit forward link signals to the mobile terminal 100.

Based on the hardware structure of the mobile terminal and the structure of the communication device, the device and the method of the invention are provided with various embodiments.

The invention provides a mobile terminal.

Referring to fig. 3, fig. 3 is a functional module diagram of a mobile terminal according to a first embodiment of the present invention.

In this embodiment, the mobile terminal includes:

the first obtaining module 10 is configured to obtain attribute information of a mobile terminal and a transmission rate between the mobile terminal and a television when the mobile terminal is connected to the television;

in order to enable the normal implementation of the invention, the television comprises a Wi-Fi module, can be connected with the mobile terminal equipment to establish a transmission channel and carry out program data transmission, wherein the transmission channel can be in a wifi-direct form or a soft-ap form. The mobile terminal includes at least one Wi-Fi module, which may be a wireless internet module 113 as shown in fig. 1. The television set may send the program data to the mobile terminal when detecting that the mobile device is connected, or may send the program data to the mobile terminal when receiving a request for sending the program data from the mobile terminal. The television can comprise a liquid crystal television, a plasma television, a network television, an intelligent television and the like. The mobile terminal can comprise a smart phone, a notebook computer, a tablet computer and the like.

In this embodiment, a Real-time transport Protocol (RTP) is used between the mobile terminal and the television, and the RTP is used to provide an end-to-end Real-time transport service for multiple multimedia data that need to be transmitted in Real time, such as voice, image, fax, etc., on the IP network. RTP provides time information and stream synchronization for end-to-end real-time transport over the Internet, but does not guarantee quality of service, which is provided by RTCP. RTP is used to transmit real-time data in unicast or multicast networks. Streaming media refers to continuous time-based media over the Internet using streaming technology. Currently, there are two main ways to transmit information such as audio and video over the Internet: downloading and streaming.

In the case of downloading, the user needs to download the entire media file to the local, and then play the media file. In the application occasions of live video and the like, the live broadcast is finished when the whole media file is generated, namely, the user can see the live broadcast program at least after the live broadcast is finished, so the live broadcast can not be realized in a downloading mode.

Streaming is a key technology for implementing streaming media. Streaming is used to allow downloading while viewing of streaming media programs. Since the Internet is based on packet transmission, the data packets received by the receiving end are often delayed and out of order (streaming is built on UDP). Streaming is accomplished by reducing latency and restoring packet timing. At the transmitting end, to reduce delay, transmission data is often preprocessed (quality reduction and efficient compression). In order to recover the time sequence at the receiving end, receiving buffering is adopted; in order to realize smooth playing of media, playing buffering is adopted.

The received data packets can be buffered by using the receiving buffer, then the out-of-order packets are reordered according to the packaging information (such as packet sequence numbers, time stamps and the like) of the data packets, and finally the reordered data packets are put into a play buffer for playing.

The reason for using play-out buffering is that the time intervals at which we get the sequenced packets are unequal, since the network is not ideal and the sequencing of the packets requires processing time. If the play buffer is not used, the playing program will be stuck, which is called delay jitter. On the contrary, by using the play buffer, when the play starts, it takes several tens of seconds to fill the play buffer (e.g. PPLIVE), which can effectively eliminate the delay jitter, thereby realizing the smooth play of the streaming media without losing the real-time performance.

And the mobile terminal sends the control instruction to the television through the RTSP.

RTSP Protocol, Real Time Streaming Protocol, Real Time transport Streaming Protocol,

the RTSP protocol works in the client-server mode, and is a multimedia play control protocol for enabling a user to control when playing real-time data downloaded from the internet, such as: pause/continue, reverse, forward, etc. Hence RTSP is also called internet video recorder remote control protocol.

To implement the RTSP control function, there are not only protocols but also a special media player (media player) and a media server (media server). The media server to media player relationship is the server to client relationship. In this step, the relationship between the mobile terminal (media player) and the television (media server) is shown.

RTSP has two types of messages: a request message and a response message. The request message is a request message sent from the client to the server, and the response message is a reply from the server to the client.

Since RTSP is text-oriented, each field in the message is some ASCII code string, and thus the length of each field is uncertain.

The RTSP message consists of three parts, namely a start line, a header line and an entity body. In the request message, the start line is the request line, and the RTSP request message method includes: OPTIONS, DESCRIBE, SETUP, TEARDOWN, PLAY, PAUSE, GET _ PARAMETER, and SET _ PARAMETER, the effect of each method is shown in the following table:

in the present invention, when a user uses the mobile terminal to connect with the television and plays a program of the television, the mobile terminal may obtain an attribute of the mobile terminal, specifically, in this embodiment, a module related to playing program data may be detected, an attribute of each module and a transmission rate between the mobile terminal and the television may be obtained, such as obtaining an attribute of a CPU, detecting a size of a memory, and the like. The model of the mobile terminal may also be obtained in the specific implementation, because the signal of the mobile terminal generally corresponds to the attribute of the mobile terminal.

A sending module 20, configured to send the attribute information and the transmission rate to the television, so that the television determines, according to the attribute information and the transmission rate, a resolution supported by the mobile terminal, and obtains corresponding compressed program data according to the resolution;

the attribute information and the transmission rate obtained by the first obtaining module 10 are sent to a television, when the television receives the attribute information and the transmission rate sent by the mobile terminal, the television determines the resolution supported by the mobile terminal according to the received attribute information and the transmission rate, for example, determines whether the mobile terminal supports the resolution of 720P, 1080P, high definition or ultra high definition, and determines the resolution of a program to be transmitted according to the received transmission rate in order to ensure that a user can watch the television program smoothly. When the resolution of the program to be transmitted is determined, the television may compress the program data to be sent to the mobile terminal according to the determined resolution of the program, specifically, in this embodiment, the image data in the program data to be sent to the mobile terminal is compressed, and the audio data may not be processed.

In specific implementation, the mobile terminal may also determine the resolution supported by the mobile terminal when the mobile terminal acquires the attribute information of the mobile terminal, and then send the resolution supported by the mobile terminal and the acquired transmission rate to the television.

A receiving module 30, configured to receive the compressed program data sent by the television.

In this embodiment, the mobile terminal receives the television through a transmission channel established between the Wi-Fi module and the television, and stores the received program data, specifically, the received program data is stored in a cache area in the memory.

When receiving the compressed program information sent by the television, the mobile terminal can trigger a corresponding operation instruction on a playing menu in the mobile terminal, and the mobile terminal selects a corresponding video from the compressed program data to play according to the operation instruction of the user. In specific implementation, the television may also compress only program data currently being played and then transmit the compressed program data to the mobile terminal, at this time, when a user wants to change channels, a channel change instruction may be triggered on the mobile terminal to transmit the channel change instruction to the television, the television compresses program data after channel change according to the received channel change instruction and then transmits the program data to the television, and the television may perform corresponding channel change or may not perform channel change.

The invention detects the attribute information of the mobile terminal and the transmission rate between the mobile terminal and the television when the mobile terminal is connected with the television; sending the attribute information and the transmission rate to a television, so that the television determines the resolution supported by the mobile terminal according to the attribute information and the transmission rate, and obtains corresponding compressed program data according to the resolution; and receiving the compressed program data transmitted by the television. Through the mode, when the mobile terminal is connected with the television to play the television program, the attribute and the transmission rate of the mobile terminal are detected, the attribute information and the transmission rate of the mobile terminal are sent to the television, and the television compresses the television program to the resolution indicated by the mobile terminal according to the attribute and the transmission rate of the mobile terminal and then sends the television program to the mobile terminal. According to the invention, the program data with the corresponding resolution ratio is sent to the mobile terminals with different attributes and the transmission rate between the mobile terminal and the television according to the attributes of the mobile terminal, so that the mobile terminal can be ensured to smoothly play the programs of the television, and the experience of watching the television programs by a user through the mobile terminal is improved.

With reference to fig. 3, based on the first embodiment of the mobile terminal of the present invention, the sending module 20 is further configured to send the attribute information and the transmission rate to the television, so that the television obtains the corresponding compressed program data from the server.

In another embodiment, when the mobile terminal is connected to a television to play a television program, the mobile terminal sends the obtained attribute information and transmission rate to the television, so that the television obtains corresponding compressed program data from the server, specifically, when the server receives the attribute information of the mobile terminal sent by the television and the transmission rate between the mobile terminal and the television, the server compresses the corresponding program according to the attribute information of the mobile terminal and the transmission rate between the mobile terminal and the television, and then sends the compressed program data to the television, and the television feeds the compressed program data back to the mobile terminal.

With continued reference to fig. 3, based on the first embodiment of the mobile terminal of the present invention, the first obtaining module 10 is further configured to obtain attribute information of the mobile terminal and a utilization rate of a CPU of the mobile terminal when the mobile terminal is connected to a television;

the sending module 20 is further configured to send the attribute information, the transmission rate, and the usage rate to the television, so that the television determines a resolution supported by the mobile terminal according to the attribute information, the transmission rate, and the usage rate, and obtains corresponding compressed program data according to the resolution.

Further, as an embodiment, when the mobile terminal plays the program information, the CPU in the mobile terminal mainly needs to perform analysis and other control, so that the utilization rate of the CPU affects the analysis and other control of the program data, and thus affects the playing of the program. In this embodiment, to further ensure that the mobile terminal can smoothly play a program of the television, when a user uses the mobile terminal to connect with the television to play a television program, the mobile terminal detects modules related to program data to be played, obtains attributes and transmission rates of the modules, and also obtains the usage rate of the CPU of the mobile terminal, and then sends the obtained attribute information, the obtained transmission rate, and the obtained usage rate of the CPU of the mobile terminal to the television, when the television receives the attribute information, the obtained transmission rate, and the obtained usage rate of the CPU of the mobile terminal, the television determines, according to the received attribute information, the received transmission rate, and the received usage rate of the CPU of the mobile terminal, a resolution ratio corresponding to the smooth television program watching capability of the mobile terminal, and then compresses program data to be sent to the mobile terminal according to the determined resolution ratio.
